Fixing missing Colo

[dl1ksv]

Latest toolchain.py has typo error:

  File "/usr/lib64/python2.7/site-packages/python_for_android-0.3-py2.7.egg/pythonforandroid/toolchain.py", line 1822, in download
filename = shprint(sh.basename, url).stdout[:-1].decode('utf-8')
  File "/usr/lib64/python2.7/site-packages/python_for_android-0.3-py2.7.egg/pythonforandroid/toolchain.py", line 207, in shprint
Style.RESET_ALL, ' ', width=(columns - 1)))
NameError: global name 'Style' is not defined

This patch fixes this error
